rtponviftimestamp: fix setting of the discontinuity flag

Browse source 
The D bit is meant to be set whenever there is a discontinuity
in transmission, and directly maps to the DISCONT flag.

The E bit is not meant to be set on every buffer preceding a
discontinuity, but only on the last buffer of a contiguous section
of recording. This has to be signaled through the unfortunately-named
"discont" field of the custom NtpOffset event.
